CIRCUIT-CLOSER FOR RECORDING-ANEMOMETERE.

Specification of Letters Patent.

Patented June 1, 1909.

application filed March 9, 1998. Serial No. 420,051.

To all whom it may concern:

Be it known that I, Jess (J. JUneENsnN, citizen of the United States,residing at Tappan, in the county of Rockland and State of New York,have invented certain new and useful Improvementsi'n'Ciicuitddakers forRecording-Anemometers, of which the following is a specification.

This invention relates to circuit makers for recording anemometers, andhas for its object the production of mechanism of particularconstruction and special arrangement and operation by which an electriccircuit is completed and then broken, in accordance with the movement ofa revolving device acted upon by; the wind.

The object is accomplished by fashioning and associating parts as setforth in the accompanying drawings, of which- Figure 1 1s a side view ofall the parts as sembled. Fig. 2 is a vertical section diametricallythrough the commutator box and adjacent parts belonging to acircuit-making device associated with this invention as ordinarilyconstructed and relating to a wind vane and means for showing thedirection of the wind. Figs. 3 and .4 are horizontal sections throughthe commutator box on the Fig. 5 is. a front view of the large dishedgear, showing different attitudes of the ball-catcher and chute. Fig. 6'is a vertical cross-section of the gearing and a side view of theballcatcher and chute. Fig. 7 is a horizontal section of the throat ofthe catcher, somewhat enlarged, showing the contact rails with which theball makes connection.

Like letters are employed to designate the same parts throughout thespecification and claims. I v

The vertical central tube or column is marked A, and it passes upwardlythrough a circular base or platform B which is supported uponthe tube.The base B and tube are stationary. The base has a raised center or hubprovided with. a conical surface I) that forms a center bearing for theturntable C. The'weight of the turntable is supported by the base, ballsc being'introduced to lessen the friction. The wind vane D is arran eddiametrically upon the top of the turnta le. The baseB has a circularseries of contacts 1;, and these. are swept by the brush E, borne by theturntable and in metallic contact I with the revoluble pulley e, whichis constantly in contact with the stationary disk the contacts I).

F, the disk being supported by base B. Conducting post's f passdownwardly through the base, and binding posts are provided for theconnection with suitable conductors in the customary manner.

The brush E is constructed of such breadth as to be always in touch withat least one of That is to say, the brush touches the contact next inadvance of it before it actually leaves the contact with which it hasconnection. Thus, the direc* tionof the wind may be read at any timeupon any common devices introduced for the purpose, as, for example, thelamp G and letter g shownin 1.

The circuit inaker constituting this invention com rises the revolvingcups H attached adjustab to arms in that are secured to the verticalshaft J that 'extends downwardly within the tube A. and has a bevelpinion at its lower end. The relatively large dished gear K meshes withthe pinion and revolves upon the suitably supported stub shaft Zr. Atthe inner ends of its, teeth the gear K has the annulargroove or ballrace L, opening inwardly toward the center of the gear. Within thegroove is fixed a projecting lug or book M, which when the gear revolvesserves to engage and raise a metal ball m that mov'ably occupies thegroove as shown in Fig. 6; As the gear K turns the ball rises until itreaches such a position that it would fall fromthe hook and from thegroove were it not for the special construction and arrangement of theball-catcher N, which is provided with a rearwardly-extending curvedapron n so situated as to cover the move L for a portion of its length.The ball 1s, therefore, constrained to remain in the groove until themouth a of the ball-catcher is encountered. Therenpon the ball fallsinto the catcher and is downwardly directed by we of the throat 0 intothe lower-chute P. t will be noted that the throat of the catcher isprovided with the contact rails Q and R arranged lengthwise within thethroat and binding posts and r are fixed upon the outside to receive anydesired conductors. It is thought to borrow clear that when the metalball passes over the rails a circuit will be completed, assuming thatthe interval between the rails is the only point of interru tion.

he large gear turns rapidl or slowly in correspondence with the revoving cups H, and it is proportioned to turn once in such period of timeduring which the wind has caused the cups to make a redetermined numberof revolutions. In ot er words, one revolution of the wheel correspondswith a certain distance moved by the wind during the same time, and thecircuit is made once during each revolution.

Let it be assumed that the wind is'very high and the large gear isturning with consequently unusual speed. It is conceivable that the hookM might reach the point at which it takes u the ball, before the arrivalof the ball at t e place of. meeting. This condition of things wouldresult, clearly, in the omission of one making of the circuit. To avoidsuch inaccuracy, the throat and chute are ivotally mounted. It will benoted in 1g. 6 that the throat O has a lateral extension S which iscentrally engaged by the end of the stationary gear shaft k.

, It will likewise be observed that the chute P has an extension 3alined with the shaft k and rotatably supported in the bearing T. Theconnection between the throat and the chute is made by the two disks Uand V, the latter being recessed circularly'to receive the former, andprovided with a set screw 22 to hold the disks in place afterad'ustment. Now, let it be considered that the t roat and chute havebeen turned toward each other and into the positions indicated inFig. 1. Under those circumstances it will be seen that while the ballhas the same distance to travel as before, the hook M must move quite adistance farther in order to arrive at the oint where the chute depositsthe ball, and the likelihood of an omission of the contact desired isthus avoided.

Havin now described this invention and explaine the mode of itsoperation, what I claim is 1. n a circuit maker, the combination with awheel having a circular groove opening toward the center of the wheeland a hook projecting into the groove, a metallic ball adapted to travelin the groove, an adjustable ball catcher having a throat rovided withcontacts arranged in the pat of the ball, and a chute disposed tocontinue the. throat and deposit the ball in the said groove at a lowerpoint, substantially as described.

2. In a circuit maker, the combination with wheel having a grooveopening toward the center of the wheel, a metallic ball adapted totravel in the groove, a ball catcher havlng a throat provided withcontacts arranged in the path of the ball, a chute disposed to continuethe throat and deposit the all in the said groove at a lower point, andmeans whereby the said catcher and chute may be adjusted with res ect toeach other and to the said groove in t e wheel, substantially asdescribed.

3. In a circuit maker, the combination with a wheel having a grooveopenin toward the center of the wheel, a metallic ball adapted to travelin the groove, a ball catcher having a throat provided with contacts arranged in the path of the ball, a chute disposed to continue the throatand deposit the all in the said groove at a lower point, and meanswhereby the catcher and chute are pivotally sup orted at the center ofthe wheel with t eir openin s registering one with the other,substantialIy as described.

4. In a circuit maker, the combination with a wheel having a circulargroove opening toward the center of the wheel and a hook projecting intothe groove, a metallic ball adapted to travel in the groove, anadjustable ball catcher having a rearwardly-ex tending apron and athroat provided with contacts arranged in the path of the ball, and achute disposed to continue the throat and de osit the ball in the saidgroove at a lower point, substantially as described.

5. In a circuit maker, the combination with a wheel, of a movable body,means adapted to encounter the body and raise it as the wheel turns,devices constructed and arranged to prevent the body from leaving thewheel laterally, an adjustable catcher rovided with contacts disposed inthe pat of the body, and a chute arranged 'to receive the body fallingfrom. a higher point on the wheel and to deposit the body on the wheelat a lbwer point, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
